A storage device including: a bridge board to receive a first command; an authenticator to receive user information; and a memory device to receive the first command from the bridge board, the memory device includes a memory controller which determines a status of the memory device, provides status information including the determined status of the memory device to the bridge board, determines the status of the memory device as an unlocked status or a locked status, the bridge board includes a transceiver which communicates with the host through an interface, a register which stores interface information, and a bridge board controller which generates a first response to the first command in a format corresponding to the interface using the interface information, and provides the first response to a host, the first response includes a status bit which inhibits or allows a write operation with respect to the memory device.

Storage device and a storage system including the same

A storage device includes a non-volatile memory including a first block, a second block and a block management area that stores an initial data write time and a final data write time for each of the first block and the second block. The storage device also includes a memory controller that determines a creation time and a modification time for first data in response to a permanently delete command identifying the first data, selects at least one of the first block and the second block to be permanently deleted by comparing the initial data write time and the final data write time for each of the first block and the second block with the creation time and the modification time, and permanently deletes the selected at least one of the first block and the second block.
